PROBLEM TO BE SOLVED: To reduce outside sizes of a connector and a plate comparing to a conventional device that the plate is engaged with the shaft part of the connector by a bayonet structure. SOLUTION: The plate 2 to be engaged with the connector 1 of the brake booster device is formed approximately in a C-shape for having a gap of its opening 2' set smaller than a diameter of inner space and that a large diameter part 12 is formed on a tip side of the shaft part 5 of the connector as well as a small diameter part 11 is formed between the large diameter part and a flange part abutting on a shell 3. A passing allowing part 11a narrower than the gap of the opening and a falling-out preventing part 11b wider than the gap of the opening are formed on the small diameter part. |
